When a client application fails to connect to a server, you can test the application for diagnostic purposes. Messages from Server Ping may provide you with enough information to solve the problem.
This test, however, cannot diagnose all types of network connection problems. Some problems may result from issues in your SAP ASE setup, rather than in your Net-Library-to-network-software connection.
When Server Ping reports an unsuccessful connection, verify that:
SAP ASE is running on the target server.
A network hardware connection exists between your client machine and the target server.
The server meets the minimum hardware and software requirements (see the Installation Guide).
The network software is installed and configured on the client and the server.
The connection information in the sql.ini file is correct for the server.
The connection information in your client’s network configuration file is correct. See the Net-Library documentation for your client.
The format of the connection information is correct for the network protocol.
